New roof-interface and mounting components are usually advisable rather than reusing ageing penetrations and attachment hardware, though the mounting-system manufacturer's instructions decide what may be reused.
Yes. Energy statutes, Board of Public Utilities regulations and utility tariffs can all change. A proposal should describe the rules as they currently stand rather than guarantee that they will hold for decades.
Yes. Mixing incompatible exhaust systems can disrupt airflow and cause one vent to pull air through another instead of through the soffits. The goal is balanced intake and exhaust that follows the roof and attic design.
